IMPROVEMENT iN liuMPs.'

The'schedule referred* to in these Letters Patent and making part of the same.

To all whom it may concern:

- Be'it known that I, JOSEPH IoAnD, of city of Donaldsonville, in the-parish of Ascension and Statex of Louisiana, have invented certain new andfuseful Improvements in Combination Pumps; and I do hereby declare that the followingjis a full, clear, and exact description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon which form a part of this specification.

'Ihe nature of my invention consists First, in a combinationl pump composed of two or more forcing, and twoor more elevating pumps;

Second, Vin a combination pump arral'lged and constructed so that at each single stroke of the working lever, whether up or down, one or more forcing and one or more elevating pumps, at'the opposite sides supply the liquid to theair-chamber; and

'.lhird, in the construction of -a safety arrangement, whereby the pistons are prevented from striking the valves and injuring them.

In order to enable others skilled in the art to which my invention appertains to make and use the same, gwill now proceed to describe its construction and operation, referring to the annexed drawing, which represents aside elevation partly in section of vmy improved combination pump.

My pump is a novel combination of the suction, forcing, and elevating pumps, whereby the power necessary to produce a given veffect is saved a continnous stream of pumped'liquid is obtained independently ot' the usual air-chamber, and a perfect equality of the strain in working up and down the pumprods is insured.

A is a frame, mounted on wheels, and supporting the platform upon which the whole apparatus is placed.

B is a valve-chest or supply-reservoir, connected by means of a hose to be attached to the orifice O, with the water or other iuid'to be pumped. 'D D are forcing and AE E', elevating pumps, communicating by means of channels l F', with the air-chamber J, and workedl pump is pivoted, as -shown at x. This leverI is supported .by'upi-ights, L, and as either end of said lever moves downward, it strikes a .by means of thc lever I, to which the rod of each segment, N, attached to a cross-bar, O, connecting said uprights, whereby any injury to the valves by the piston of the pump striking them is prevented.

- The channels F F' are provided with valves, al' d',

opening into the air-chamber J, to prevent the return llow of the liquid after the stroke of the pump is finished.

The pumps I) D are provided with solid pistons, while those of the pumps E E' are of the kind known as bucket-pistons, te, provided with an upward opening valve. Y

.All the pumps have at the bottom the usual inward opening valves c e, communicating with the supply-reservoir B.

l is the opening through which the liquid pumped is conveyed to its destination.

Itis. obvious that when the lever I is worked up andvdown, there will be at each stroke, two pumps at the opposite sides of the center of thc lever, furnishing the liquid to the air-chamber J, alternatively with the two others.

Foi-'use in a sugar factory, for pumping molasses orI othery liquid, or when only a comparatively smallv power has to work the pumps, one, two, or more of them may be stopped by disconnecting the same at :v, with the leverI, thus-leaving only the number of pumps deemed to be necessary; and for draining, ex.

tiuguishingof lires, or other-similar purposes, the

pumps previously disconnected may be again attached with the greatest ease.

'I he platform upon which my apparatus rests may be taken off the wheels and set on the iloor 85o., if so desired.

Having thusf'ully described my invention,

That I claim as new, and flesh-etc secure by Letters latcnt, is-

A pump, consisting of two or more forcing and two or more lifting pumps, iin combination with aircharnber J, and pipes F F, said pipes and'pumps being .provided with suitable' Valves, and all arranged as -and for the purpose set forth.

In testimonythat I claim the foregoing as my o wn, I afix my signature in presence of two witnesses.
